1 of 2 Find the length of the shortest side if the area of the rectangle is 144m2
х
x + 10

Given,

Length and breadth of the rectangle are (x) and (x+10)

Area of the rectangle ( A ) = 144

We know ,

Area of rectangle ( A ) = L*B

                        or , 144 = x ( x+10 )

                        or , 144 = + 10x

                        or , + 10x - 144 = 0

Solving the equation , we get ,

x = 8 and -18

The side has to be positive so ,

x = 8 m , which is the shortest side !

Step-by-step explanation: We were given the area of the rectangle and length & breadth in expression . By using the formula of area of rectangle , we got the equation which then gave 8 and -18 as answers when solved and since the rectangle had positive sides 8 m was the correct value . Also its the shortest side and the other side is simply ( 8 + 10 ) which is 18 m but the question has only asked for the shortest side !

step-by-step explanation:

at each of the parallel lines adjacent angles are supplementary. the angles have special names identifying their positions with respect to the parallel lines and transversal. they are corresponding angles, alternate interior angles, or alternate exterior angles. an angles is congruent to its matched angle.
